“10 years ago, my colleagues and I looked at the prognosis for climate change, and it looked pretty hopeless. There really was no way out. But something happened – something good.”

Neuroscientist David Linden sheds light on the biology behind phenomena that medicine has long struggled to explain, from voodoo death and broken heart syndrome to the placebo effect, and why grief shows up in autopsy results

NASA astronomer Michelle Thaller makes the case that quantum entanglement may be the underlying fabric from which spacetime itself emerges. 

Jim Al-Khalili explains how the past and future are more fluid than we may think.

Jim Al-Khalili introduces the technologies emerging from the second quantum revolution.

Brian Cox examines why, despite billions of stars and trillions of planets, we have found no evidence of other intelligent life.

Sam Kean examines how rogue archaeologists are recreating the sounds, tastes, smells, and practices of the ancient past.

Thanks to modern tech, Earth is now considered a ‘detectable’ planet. Astrophysicist Sara Seager explains how this idea can lead us to discovering life elsewhere in our universe.

"The production of the silicon wafers that are used in the chip manufacturing process requires extraordinary levels of purity."

At COP30, Indigenous leaders came with a message the world can’t ignore: 5% of the global population is safeguarding 80% of Earth’s biodiversity. A $1.8B pledge was made to support their land rights — but will the money follow their lead?

Military satellite research brought us GPS. Astronomers influenced medical imaging tech. What would be invented after we discover alien life? Professor Sara Seager explains the consequences of such a groundbreaking discovery.

Chris Miller explains the hidden reason that global superpowers are obsessed with Taiwan.

Astronomer Jill Tarter explains why SETI is really about technology, patience, and learning how to tell alien signals from our own.

30 years ago, we didn’t know other stars had planets orbiting them. Now, we may be on the verge of finding Earth’s Twin. Sara Seager explains.

"In the process of mapping the heavens, it doesn't take long to realize the data problem they generated."

"The process of systematizing, correcting errors, finding approximations, and making them work as civil systems that was what really drove me to start looking at human calculation and what was the foundation that it laid for the modern computer age."

"This will help people take meaningful steps to slow the rate of aging and increase what we call their health span or their kind of time of life expectancy free from disease."

“How can all the diversity and, sort of, seeming order that's out there in the world emerge from a process dependent upon chance?”

“The next revolution will be quantum computers that will make the digital computer look like an abacus.”

Having explored the Mariana Trench, the summit of Everest, and the edge of space, Victor Vescovo knows what awe feels like in its most dramatic forms. What surprised him most was how often that same feeling appears in everyday life.

Ninety million years after our lineages split, humans are beginning to listen to whales in a new way. Marine biologist David Gruber shares the work that has become his life’s pursuit: learning how to hear the planet’s largest mammals.

“Until very recently, I thought I would die with the same genome that I was born with.”

“Old systems of the past are collapsing, and new systems of the future are still to be born. I call this moment the great progression.”

Everything ever seen — every star, mountain, and face — makes up less than 5 percent of the universe. Astrophysicist Janna Levin reminds us that the rest — dark matter and dark energy — is invisible, mysterious, and everywhere. We are the luminous exception in a universe of darkness.

“Progress happens when we choose to make it happen. It happens through choice and effort. And ultimately, to make progress happen, we have to believe in it.”

“People got skeptical, fearful, doubtful of the very idea of progress in the 20th century and we allowed that to slow down progress itself.”

“Chance invents and natural selection propagates that chance invention.”

“The messy reality of it is that all of these very smart people, including Isaac Newton, were talking to other people.”

“Over the last 10 or 15 years, scientists have really started to understand the fundamental underlying biology of the aging process. And they broke this down into 12 hallmarks of aging.”

If you’ve gotten goosebumps when hearing a story about a stranger’s selfless heroism, or you’ve felt your chest swell at a concert, when the audience’s voice and the musician’s instruments align, you have felt awe. And, according to professor Dacher Keltner, who has spent his life studying it, it’s one of humankind’s most unifying traits:
